A carat is a unit of weight for precious stones, most often for diamonds. 1 carat = 200 milligrams (0.200 grams).
Pure 24k Gold Nugget
A karat, when used with gold, is a unit of purity. Pure gold is known as 24-karat. Since pure gold is very soft and easily malleable, gold jewelry is usually mixed with a metal like copper or silver. Each karat indicates 1/24th of the whole. So let’s take 18k, or 18 karat gold as an example. This means that it is made up of 18 parts gold and 6 parts metal, and contains only 75% of real gold (because 18/24 = 75%).
